Sharing a design on Twitter, Nick Roberts pronounced he had assisted a tennis star with a self-service checkout.
“Just finished Rafa Nadal’s selling for him on a self use tills on a tesco demonstrate in Wimbledon village. Surreal,” he said.
He added: “It was really exciting. He bought a 6 container of Diet Coke. Didn’t need a bag. Environmentally unwavering and overwhelming during tennis.”
